Take the penultimate letter of every line. It spells out B-E-R-R-Y (Berry Stevens).
Reg Blatter was personally responsible for the death of Victor Timothy. Reg did not perform the killing in person and in fact had not seen Timothy for the last 3 years. Nevertheless, he managed to send the murder weapon safely through the post along with a greeting card.
Timothy died by using the weapon in manner as it was supposed to be used. The card ended up touching the murder weapon, but the greeting card never reached its intended destination. Timothy had no reason to kill himself.
How did Reg kill Timothy?
